Because the higher the food chain gets, the less energy is being transferred , therefore, there are less organisms at the top of the food chain.
Cacti grow in the desert, which is a very hot climate. Not the best for both gaining and maintaining water supplies, due to the fact that water becomes vapour very quickly in conditions such as a desert (unless we're talking about polar deserts).
Keeping their stomata closed during the day stops water vapour from escaping their cells. While this does inhibit growth and stop new water molecules from entering, it allows the cactus to maintain a healthy amount of water within itself.
Answer:
<h2> any organism containing the DNA of interest</h2>
Explanation:
- Such type of process in which the modification of the genes of the organisms takes place is known as genetic modification and also called genetic manipulation or genetic engineering.
- In such type of the process, the branch of biological science that is known as biotechnology is used.
- In this mechanism, genes of interest are separated from the certain organism and then this gene of interest is inserted into the host organism and such type of DNA that is formed after the addition of foreign genes or DNA is called recombinant DNA.
- Such type of DNA is used in the production of genetically modified organisms and some other fields for the benefit of human beings.
Answer:
<u>positive, negative, or no effect</u>
Explanation:
The kind of effect that a chromosomal change can have on an organism is either positive, negative, or no effect.
The 3 main chromosomal disorders seen in humans are :
- <u>Down's Syndrome</u>
- <u>Klinefelter's Syndrome</u>
- <u>Turner's Syndrome</u>
Let's think of it like this. We have an energy crisis, but how can we solve it? There are three steps. First, we need to recognize that we HAVE a problem that needs to be fixed. Then, we need to determine what's causing the problem. Finally, we need to change how we act in order to solve the problem. Now, let's look at the options.
Is A correct, leaving our behavior unchanged? NO: if we know the cause of the problem, we still need to solve it! What about B: the problems are ignored? NO: you can't solve a problem unless you know it's a problem. C? NO: to solve a problem, you need to find out what's causing it. Finally, let's look at D: behavior is changed after cause is identified. This is correct: not only do we know why it's happening, but we're fixing it!
Answer: D
